Look Up Table Integration



We are using WebTrends for web analytics and are trying to opt for Piwik now. There is a feature in WebTrends wherein we can integrate a lookup table and then create multidimensional custom reports based on the fields in the lookup table. For example the lookup table has details of all employee, their id, mail, career level, country, city , etc and we can create reports like username vs country or username vs career level etc. Is such kind of lookup table integration possible in Piwik? Is there any way of creating custom reports in Piwik? If not , is there any feature which is somewhat close to what i mentioned above?
